Guns N' Roses frontman Axl Rose was so pissed this weekend during a concert he almost walked off stage -- after being pelted with a water bottle.
It all went down in Sao Paulo, Brazil, when someone in the audience launched a liquid filled plastic projectile at Rose during the opening number.
Axl was ticked and stopped the show while screaming "You wanna f**k up the show for everybody? You wanna f**k with me and my boys? We will leave."
They didn't -- and the show continued moments later.
